The use of environmental modeling for systematization of tacit knowledge: identification of optimal corridor for transmission lines of electricity

The need for expansion of the electricity sector requires constant improvement for designing methods and project developments, such as electricity transmission lines. The dissemination of geoinformation technology supports the modernization of the process, yet the preservation of tacit knowledge is a key challenge to be considered. The patterns resulting from projects implemented in the past can be found in the landscape. This paper hypothesizes the use of geotechnologies to extract the tacit knowledge from linear engineering projects printed in the landscape through landscape analysis, therefore use the information in a multicriterial decision framework towards modeling new corridors for transmission lines of electricity. This procedure can represent an opportunity for establishing metrics for interfacing new technologies and productivity gains to modernize the planning process of the sector of energy distribution. This research is based on a multi-temporal analysis. The model developed is dynamic and geographically explicit in order to recognize not only the spatial occurrence pattern of the phenomenon, but also the variation along their history. This study employs robust methodologies, such as Weight of Evidence and Least Costly Path to study the spatial pattern of the energy transmission lines implementation across the landscape. The results demonstrate the feasibility of GIS and landscape analysis, as well as the possibility of identifying geographic variables not considered in the existing regulation, and indicate preferable locations for new corridors.

电力行业扩张的需求，对输电线路等工程的设计方法与项目开发流程提出了持续优化的要求。地理信息技术（geoinformation technology）的推广虽为该流程的现代化提供了支撑，但隐性知识的留存仍是亟需重视的关键挑战。过往实施的线性工程项目所形成的空间特征，留存于地表景观之中。本研究提出假设：通过景观分析，借助地理技术（geotechnologies）从留存于地表景观中的线性工程项目中提取隐性知识，进而将该信息应用于多准则决策框架，以建模新建输电线路走廊。该方案可为构建新技术对接与效能提升的评价指标提供契机，助力电力配电规划流程的现代化升级。本研究基于多时态分析方法展开。所构建的模型具备动态性与地理显式性，不仅可识别该现象的空间分布模式，还能解析其随时间演变的过程。本研究采用稳健的方法论体系，包括证据权重法（Weight of Evidence）与最小成本路径法（Least Costly Path），以探究输电线路建设在地表景观中的空间分布模式。研究结果证实了地理信息系统（GIS）与景观分析的可行性，同时发现了现有规范中未纳入考量的地理变量，并为新建输电线路走廊指明了优选区位。
